Description
The HSDL-7000 performs the
modulation/demodulation
function used to both encode and
decode the electrical pulses from
the IR transceiver. These pulses
are then sent to a standard UART
which has a BAUDOUT signal
available externally. This signal is
16 times the selected baud rate.
In applications where the
16XCLK is not available, an
external means of generating the
16XCLK must be designed.
The HSDL-7000 is comprised of
two state machines – the serial IR
encode and the serial IR decode
blocks. Each of these blocks
derives their timing from the
16XCLK input signal from the
UART. The Encode block is
driven by the negative edge
triggered TXD signal from the
UART. This initiates the modula-
tion state machine resulting in
the 3/16 modulated IR_TXD
signal which drives the IR trans-
ceiver module, HSDL-1000. The
IR Decode block is driven by the
negative edge triggered IR_RCV
signal from the HSDL-1000. After
this signal is demodulated and
stretched, it drives the RCV signal
to the UART.
